On the other hand, since the plate cam also rotates in synchronization with the forward movement of the transport rod,
The large diameter part of the plate cam enters under the package and supports the package from below. Therefore, the transport rod passes under the package and advances.

Further, when the transport rod advances, the package further advances with the rotation of the stopper gear, and the end of the package catches the stepped portion of the connecting plate. At this time, since the small diameter portion of the plate cam comes into contact with the package, the package gradually descends and comes into contact with the inspection table. Next, as the next transport rod advances, the package is hooked on this next transport rod and transferred to the inspection passage. After that, the same operation is repeated and the packages are sent one after another in front of the transport rod.
